//-----------------------------------------
//        SHADER
//-----------------------------------------
// this vmt is written for the follow shaders, you MUST select only ONE

//"LightmappedGeneric"
	// use this ONLY for BSP brush surfaces
	// this shader references the BSP brush lightmap points for light valves and builds gradient shades between each point as a lighting solution

//”VertexLitGeneric"
	// use this ONLY for models imported as props into source
	// this shader calculates each vertice’s light valve and builds gradients shade between each point as a lighting solution

//"UnlitGeneric"
	// this material does not render lighting properties
	// its surface will not be shaded or effect nearby materials

{
//-----------------------------------------
//        MAIN PROPERTIES
//-----------------------------------------

"$basetexture" " folder\texture "
	// defines the base texture path from the \Materials folder eg “folder\texture"
	
"$surfaceprop" "concrete"
	// defines the physics, sound effects and audio distortion of the material, see Scipts\surfaceproperties.txt

	//AP// "%keywords" "texture_search"
	// use to search and find keywords in the material browser


//-----------------------------------------
// NORMAL MAP PROPERTIES
//-----------------------------------------
// Normal maps tells the engine how to display the light hitting the polygons
	// 3 color channels - Red – left to right, Green – up to down and Blue – depth
	
//"$bumpmap" "folder\texture_normal" 
	// defines the normal map texture path from the \Materials folder eg “folder\texture"

	//AP//"$bumpscale" "1.0"
	// use to scale the normal map texture


//-----------------------------------------
// REFLECTIVE PROPERTIES
//-----------------------------------------
// materials like glass, metal, plastics, liquids and glossy surfaces like tiles or varnished wood

//"$envmap" "env_cubemap"
	// uses cubemaps for reflective textures, you can create you own, see below

	//AP// "$envmaptint" "[.7 .7 .7]"
	// RGB changes the hue of the reflection (the gradation of color within the visible spectrum)
	// eg. a red material would tint the cubemaps red

	//AP// $envmapcontrast" 0.5
	// set the reflections contrast (the difference in visual properties\shade that makes an texture)

	//AP// "$envmapsaturation" 0.3
	// set the reflections saturation (the purity/intensity of the specific hue)

// If you want have a reflection mask, choose ONE of the follow target paths

	//"$envmapmask" "folder/texture"
	// use this if you want to target a separate texture to define the opacity mask (don’t use the alpha channel)

	//"$basealphaenvmapmask" 1
	// use this if you want to target the basetexture's alpha channel to define the opacity mask

	//"$normalmapalphaenvmapmask" 1
	// use this if you want to target the normal map texture’s alpha channel to define the opacity mask
	// if you have a normal map you must put the reflective mask on its alpha channel

//-----------------------------------------
// TRANSPARENT PROPERTIES
//-----------------------------------------
// materials like glass, plastics or liquids as well as fences or surfaces with gaps across it

//"$translucent" 1
	// use the alpha channel of the $basetexture as transparency
	//if the base texture's alpha channel is being used, you must change it so you can use this effect

	//AP// "$alphatest" 1
	// use to make the mask to run a hit test, so you can shoot through it

	//AP// "$alpha" 0.5
	// set the overall base texture's opacity, don’t use $translucency
	
	//AP// "$additive" 1
	// use to render the base texture additively (like a Photoshop effect)

//-----------------------------------------
// ILLUMINATION PROPERTIES
//-----------------------------------------
// this is used make a section or all of the material seem bright
// eg, a light bulb/sign that is on or LED lights on a computer prop (these objects should not be shaded) 
// this does not cast light, it just blocks the section from being shaded so it appears brighter or renders in a dark place

//"$selfillum" 1
	//use the base texture's alpha channel to define the illumination across the surface
	//if the base texture's alpha channel is being used, you must change it so you can use this effect


//-----------------------------------------
// OTHER PROPERTIES
//-----------------------------------------
	
	//AP// "$color" "[100 100 100]"
	// use to scale the red, green, and blue channels of the material

	//AP// "$nocull" 1
	// use to make the texture render on the front and back sides 

	//AP// "$decal" 1
	// use for textures that need be rendered as a decal

	//AP// "$nodecal" 1
	// use to apply no decals on the texture, like a fence or transparent material 

	//AP// "$decalscale" .25
	// use .25 scale so the texture resolution matches hammer’s texture scale
